Neil Turok - Dark Matter and the Formation of Structures

In this video series entitled "Conversations at Niels Bohr's Office" Johan Samsing from the Niels Bohr Institute presents conversations with some of the most influential physicists and thinkers of over time on topics related to the fundamental physics of our Universe.
Each episode is recorded at the historical Niels Bohr's Office and based on one long take with no script, with the intention of creating a more natural conversation about whatever topics the guest wants to highlight.
3. Episode: "A New Solution to Origin of Dark Matter and the Formation of Structures?"
Neil Turok is a South African physicist, known for his groundbreaking work on early-universe physics, including the cosmological constant and a cyclic model for the universe. In 1992 he was awarded the Maxwell medal for his contributions to theoretical physics. In 1994 he was appointed Professor of Physics at Princeton University, then held the Chair of Mathematical Physics at the University of Cambridge starting in 1997. He was appointed Director of the Perimeter Institute in 2008. In 2020, Turok was appointed as the Inaugural Higgs Chair of Theoretical Physics at the University of Edinburgh.

It is nice to hear a reasonable explanation, that does not sound like magical thinking. Also one that is actually focused on testiblity.

Thank you for this interview. There's an unforgivable under representation of Neil Turok's brilliance on RUclips.

[@NomenNescio99]

Could not agree more!

[@andymccracken4046]

Thanks, I'm really excited about this work by Neil Turok and look forward to seeing more details whenever they appear.

I like where Niel is going with his work. Nature seems to prefer simplicity and all things being equal, nature will always take that route.

Finally! A very compelling and “simple” idea to the nature of the universe. No strings or 14 dimensions which are untestable. I can’t wait for the galaxy survey results. What a brilliant mind.

Do recent discoveries of very large scale voids upset Neil Turok’s requirement of a flat, isotropic universe? I seem to recall Sabine Hossenfelder reporting on these voids in one of her recent videos (2023/2024).

Great talk. May I suggest better microphones? The sound is subpar.

The biggest (only?) hurdle is assuming gravity to be an attractive force. It can be seen rather as the dissipative force of the elastic solid of spacetime or dark energy as it resists the compressive forces due to quantization after a large perturbation (see Padmanabhan (2004) for an example of ‘elastic solid’ spacetime being equivalent to Einstein’s general relativity calculations). Scientists are already exploring the ‘repulsive’ forces they are attributing to dark energy (elastic solid spacetime in this view). Why not extend that ‘repulsiveness’ to dissipative gravity rather than assuming opposing forces? Gravity only appears to be attractive due to the conservation of energy as spacetime/dark energy is pulling everything apart while the strong force and aspects of electromagnetism keeps quantized matter in balanced, ‘bounded’ systems. This dissipative gravity and its amplified cousin, the weak force, along with the symmetric dissipation of the Higgs field and the dark matter field are the physical sources of entropy. So along with the assumption of special relativity, the energy of the strong force with relatively minor contributive forces of electromagnetism is symmetric with the dissipative forces of electromagnetism, gravity, the weak force, the Higgs field, the dark matter field, and the cosmological constant. With this view there is no longer a need to assume singularities, extra dimensions, or a number of other mathematical artifacts that arise due to the current theories, gravity is easily reconciled with the other forces, and everything at every scale is a dissipative system, including people-a complex system of embedded dissipative systems ensembles. Elegant. Beautiful.

Hi there did you know about neutrino 4-experiment, conducted by Anatolii Serebrov...

[@NomenNescio99]

Pardon a layman, but hasn't miniboone at fermilab already found pretty strong evidence for sterile / right handed neutrinos?

[@loushark6722]

Neil's ideas are so interesting.
